If two resistors of 35 &#x3A9; and 15 &#x3A9; are joined together in series and then placed in parallel with a 40 &#x3A9; resistor, the effective resistance of the combination is :

Philoid · Accepted Answer

When the resistors are in series, then the combined resistance = 35 Ω+15 Ω = 50Ω

Now 50Ω and 40 Ω are connected in parallel, so the combined resistance
